Steroids are the anti-inflammatory drugs used in the treatment of

  1. Rheumatic fever

  2. Acute glomerulonephritis

  3. Rheumatoid arthritis

  4. All of the above
Reveal answer Fill a bubble to check yourself
D Correct answer
Explanation

Rheumatic fever is an inflammatory disease, that can occur after an infection of the throat with bacterium, Streptococcus pyogenes or group A streptococcus.  Various corticosteroid, such as prednisone may be given for treatment.
Acute glomerulo-nephritis is inflammation of the glomeruli. Corticosteroids and immune-suppressing drugs are taken to control inflammation.
Rheumatoid arthritis is a chronic inflammatory disorder that typically affects the small joints in the hands and feet. NSAIDs or non-steroidal anti-inflammatory drugs are given to relieve pain and inflammation and also, corticosteroid, such as prednisone.
Thus, the correct answer is option D

A useful drug that damages gastric mucosa, if taken along with alcohol is

  1. Antihistamine

  2. Morphine

  3. Aspirin

  4. Valium
Reveal answer Fill a bubble to check yourself
C Correct answer
Explanation

Aspirin is the non-steroidal anti-inflammatory drug. It is used to reduce fever and pain. Aspirin, a longtime antidote for the side effects of drinking, may actually enhance alcohol's effect. Aspirin significantly lowered the body's ability to break down alcohol in the stomach. Aspirin interferes with the action of an enzyme in the stomach lining called alcohol dehydrogenase and erodes the mucosal lining of the stomach, which breaks down a portion of each drink consumed before it enters the bloodstream. Aspirin probably has no effect on alcohol once it has been absorbed and is circulating.

Multiple Choice Question

Which one of the following is now being commercially produced by biotechnological procedures?

  1. Nicotine

  2. Morphine

  3. Quinine

  4. Insulin
Reveal answer Fill a bubble to check yourself
D Correct answer
Explanation

Biotechnology refers to technology used to manipulate DNA. The procedures are often referred to as genetic engineering. DNA is the genetic material of all living organisms and all organisms use the same genetic code. Genes from one kind of organism can be transcribed and translated when put into another kind of organism. For example, human and other genes are routinely put into bacteria in order to synthesize products for medical treatment and commercial use. Human insulin, human growth hormone, and vaccines are produced by bacteria.

To treat myasthenia gravis, 

  1. Acetylcholine esterase activity is inhibited

  2. Receptors on motor end plate are reduced

  3. Secretion from nerve terminals is reduced

  4. Secretion from nerve terminals is enhanced
Reveal answer Fill a bubble to check yourself
A Correct answer
Explanation

Myasthenia gravis is a disease caused due to the antibodies produced by an immune system that blocks or destroy the receptor sites for a neurotransmitter called acetylcholine. The enzyme esterase or acetylcholine esterase break the acetylcholine and deactivates the neurotransmitter to stop muscle activation. 

During treatment of myasthenia gravis, it is prevented by using a chemical drug acetylcholinesterase inhibitor. These acetylcholinesterase inhibitors increase the amount of acetylcholine available and so help muscle activation and contraction.
So the correct option is 'Esterase activity is inhibited'.
